Voltage = current * resistance
Voltage = 12 * 4
Voltage = 48V

As per ohm's law we can say that voltage across the ends of a resistor is always product of the resistance with current flows through it.

So we can write

[tex]V = i*R[/tex]

given that

i = 12 A

R = 4 ohm

now we can say from the above formula

[tex]V = 4 * 12 [/tex]

[tex]V = 48 Volts[/tex]
